Mud samples are taken at two sites in Roebuck Bay, which has the richest biodiversity of any mudflat in the world. These samples are full of marine invertebrates known as ‘benthos’ that are sorted in a laboratory at the Broome Bird Observatory then sent to scientists for identification. Long term monthly sampling enables monitoring of changes in invertebrate abundance. Ongoing studies have revealed that the total density of macrobenthic animals (1,287 individuals/m2) is high by global standards for a tropical mudflat and species richness is very high – estimated to be between 300-500 species (Draft ECD, Bennelongia 2009).
Project supported by
Roebuck Bay Working Group is comprised of Traditional Owners and government, local community, conservation groups and business. We work collaboratively to solve issues, raise awareness and encourage research and monitoring which supports responsible management and protection of Roebuck Bay.
